Overview
The IRKT162/12 is a high-power Silicon Controlled Rectifier module from the IRK.162 series, manufactured by Vishay General Semiconductor - Diodes Division. It features an IT(AV) rating of 160 A at a case temperature of 85 °C and supports a maximum repetitive peak reverse voltage (VRRM) of 1200 V. The device utilizes the New INT-A-Pak industrial standard package with electrically isolated DBC ceramic construction, providing a 3500 V RMS isolating voltage. Key electrical characteristics include a maximum RMS on-state current of 355 A and a junction operating temperature range of -40 to 125 °C.
Feature Summary
- Electrically isolated by DBC Ceramic (Al2O3) for enhanced safety
- High surge capability with robust I2t ratings for fusing protection
- Industrial standard NEW INT-A-Pak package for simple mounting
- Glass passivated chips for improved reliability
Applications
- DC Motor Control and Drives
- Battery Chargers
- Welders
- Power Converters
- Lighting Control
Procurement Notes
Verify the specific voltage code suffix against the ordering table, as the IRK.162 series includes variants for 1200 V, 1400 V, and 1600 V. Confirm the required circuit configuration, as the series offers Thyristor/Diode and Thyristor/Thyristor options. Ensure thermal interface materials are compatible with the specified mounting torque requirements for optimal heat dissipation.
Selection Notes
Select based on the required average on-state current and maximum repetitive peak reverse voltage. Consider the thermal resistance values for both junction-to-case and case-to-heatsink interfaces when designing the cooling system. Evaluate the gate triggering parameters to ensure compatibility with the control circuitry, particularly regarding peak gate power and current limits.
Part Context
This component belongs to the IRK.136, .142, and .162 series of NEW INT-A-Pak Power Modules. These modules are designed for high-current applications requiring reliable switching performance. The series integrates high-voltage power thyristors and diodes into a compact, standardized form factor suitable for various industrial power electronics systems.
Replacement Considerations
Consult official manufacturer documentation for direct substitutes within the same series or equivalent packages. Verify that any replacement part matches the critical ratings for current, voltage, and thermal resistance.
